The sourceforge files, issues, etc, have been removed, the project will be deleted soon. I do not agree with their excessive use of ads (at least 10 per page).
The original version can be downloaded from github github.com/codelv/inkcut/releases/download/v1.0/inkcut-1.0.tar.gz or from the inkscape forums www.inkscapeforum.com/viewtopic.php?f=31&t=4987.
Sorry for the confusion!
